Indefinite insult, often used in horrible rap battles on YouTube and Ebaum's to describe someone who is cartoonish, or has cartoon-like qualities. It is unknown whether or not it will offend the person it is said to.

You have a bull on your shirt... you look like a firt... from a cartoon. A coon, and it ruins like prunes... you live with racoons! Animal boom? You live in Kalamazoo.. you foo!
